You can use Diquat Water Weed and Landscape Herbicide for weeds around a pond. Please refer to the Diquat product label for exact dilution ratios as they will vary depending on where you are treating. In general you will dilute 0.75 oz. (22 mL.) Diquat Water Weed and Landscape Herbicide plus the labeled rate of a nonionic surfactant per 1 gal. of water.
